FASTENING STRUCTURE OF SHAFT WITH BEARING

摘要

A fastening structure of a shaft and a bearing is provided to minimize abrasion of the shaft and the bearing by fixing the bearing to the shaft using a key so that an inner race of the bearing rotates during rotation of the shaft. A fastening structure of a shaft(200) and a bearing(100) comprises a key(300). The bearing includes an inner race(102) having a first groove(106) and an outer race(104) which is disposed apart from the inner race, wherein a plurality of balls is interposed between the inner race and the outer race. The shaft is inserted into the bearing and has a second groove(206) forming a predetermined space in combination with the first groove. The key is inserted into the space, which is formed between the first and second grooves, to fix the shaft to the inner race of the bearing.
